Microphones and stethoscopes are regularly used by physicians to detect sounds when monitoring physiological conditions. These monitors are coupled directly to a person's body and measure in certain bandwidths either by listening or by recording the signals. The physiological processes, such as respiration and cardiac activity, are reflected in a different frequency bandwidth from 0.01 Hz to 500 Hz.
